Given parameters:

Actual length = 260m

Drawing length = 286mm

Unknown:

Scale used = ?

Solution:

A scale compares drawing length to ground distance;

To find the scale,

Express the two quantities in the same unit;

actual length = 260 x 10⁻³m = 0.26mm

Now;

drawing length : actual length

286mm : 260 x 10⁻³mm

divide by 286;

1mm on drawing : 9 x 10⁻⁴mm on map

or;

1mm on drawing is 0.9m on ground
